　　(1) Preparation. Use pure water and analysis of pure sulfuric acid to configure the electrolyte electrolyte, the ratio is: 500ml pure water, and add 0.5ml pure sulfuric acid. Prepare standard rubber exhaust valve for later use. Tools: Zi Zi, straws (can be replaced by a disposable needle tube), transparent polyethylene tube, and the diameter should be suitable for the straw (needle tube) suction, ABS glue.

　　(2) Pry the cover above the battery along the exhaust hole. The cover of some batteries is ABS adhesive, and some batteries are connected by buckle. Pay attention to pry open the cover, do not damage the cover. This is a rubber hat for 6 exhaust valves.

　　(3) Open the rubber hat and expose the exhaust holes. You can see the inside of the battery through the exhaust hole. The exhaust valves of some batteries can be spinned. There are some filling around the rubber caps of some batteries. Pay attention to the storage filling.

　　(4) The electrolytic solution inhaled with a dropper is injected into the electrolyte from the exhaust holes. The electrolyte should just cover the pole plate 1mm.

　　(5) Cover the battery with a stolen electrolyte with a stolen electrolyte to prevent the dust from falling into the exhaust holes and static for 12-24 hours in order to fully penetrate the electrolyte. Observe the electrolyte inside the exhaust holes again, there should be a flowing electrolyte (free acid), otherwise the electrolyte should be supplemented.

　　(6) In the condition that the exhaust holes are not covered, the 16.2 voltage voltage voltage limit is charged. When charging, it is best to put the battery in a acid -resistant container to prevent overflowing electrolyte pollution. The battery charging current drops to 400 ~ 300 mAh, or the voltage reaches 16.2V for more than three hours. It is believed that the battery is full for the first time.
